The only problem with huge discrepancies in course length that I can see is if the weather conditions change from one day to the next. But I guess that's just the luck of the draw. If it rains today as predicted, TCC will be significantly easier, I think. Those tiny greens were fast yesterday, and lots of shots released and rolled through. A little bit softer and you've got a better chance of holding when you're coming in from 200+ yards. The fact that someone posted a 67 yesterday on that course is pretty amazing.
I did a quick Google search, and the Australian kid I was watching is Oliver Goss, a sophomore at U Texas. He had one of the best recoveries I've ever seen. On the 3rd hole, which is an impossible 450 yard par 4, he hit iron(!) off the tee into the left rough. Anything off the fairways there is a crapshoot, and more often than not you're lucky to advance it 100 yards. He had 200 yards to the green, and flew it long. We figured it went in the water behind the green, but apparently it stayed up. He tried to hit a huge full-swing flop shot for his 3rd and instead hit an epic shank. His ball was heading for the 4th fairway when it hit a tree and came back toward 3. It came to rest on the cart path, so he got relief from that. So he was hitting his 4th from about 10 yards off the green in heavy rough over a bunker to a green that slopes away from him and water to worry about if it came out left. And his last shot was a shank. He tried the super nuclear flop again, hit it perfectly, nailed the flagstick dead on, and had a one-inch putt for bogey. He could easily have had an 8 or worse.
